The IEEE 802.15.4 standard represents a networking protocol. I don't
exactly know why drivers for this protocol are stored into the root
'driver' folder, but better will be to store them with other
networking stuff. Currently there are only 3 drivers available for
IEEE 802.15.4 stack, so lets do it now with the smallest overhead.
